* Minor enhancement
* Added max_requests to avoid ECONNRESET for a server that allows a limited
number of requests on a connection. Pull request #42 by James Tucker.
* Request failures are now raised with the backtrace of the original
exception. This gives better insight into the reason for the failure.
See #41 by Andrew Cholakian.
* OpenSSL is no longer required. If OpenSSL is not available an exception
will be raised when attempting to access HTTPS resources. Feature request
by André Arko
* Bug fixes
* Explain the proper way of sending parameters depending upon the request
method. Issue #35 by André Arko.
* Handle Errno::ETIMEDOUT by retrying the request. Issue #36 by André Arko.
* Requests retried by ruby 2.x are no longer retried by net-http-persistent.
* Finish the connection if an otherwise unhandled exception happens during a
request. Bug #46 by Mark Oude Veldhuis.
* detect_idle_timeout now assumes a StandardError indicates the idle timeout
has been found. Bug #43 by James Tucker.
